Invincible Season Four is set to premiere in March 2026 and will continue the story of Mark Grayson (Invincible) after the catastrophic events of Season Three.

Season Three concluded with the “Invincible War,” including new threats like Conquest and the devastation that came with his arrival. Many heroes are injured, Earth must recover, and Mark faces profound moral challenges.

In Season Four, viewers can expect:

• The introduction of Thragg, the formidable Grand Regent of the Viltrum Empire, voiced by Lee Pace.
• Expanding threats including a Sequid invasion, continued fallout from the Viltrumite War arc, and more interplanetary conflict.
• The return of major characters: Mark Grayson, Omni-Man (his father), Atom Eve, Debbie Grayson, and others. New cast additions include Matthew Rhys in a yet-undisclosed role.
• Greater stakes and possibly darker moral territory for Mark, as he grapples with protecting those he loves while confronting powerful enemies and possibly making very difficult choices.
